Synthetic Monitoring
Catch issues before your users do
Synthetic monitoring runs automated Lighthouse audits from controlled environments on a schedule you define. Get consistent, reproducible measurements that aren't affected by user conditions. Perfect for catching performance regressions after deployments - before they impact real users.

Automated Lighthouse audits at your fingertips
Track performance metrics, Lighthouse scores, and page load filmstrips over time. See exactly how your site performs in controlled conditions.
Lighthouse Details

A deployment went out, and now everything is slow
By the time users complain, the damage is done. Synthetic monitoring catches regressions immediately after they happen.
Performance regressions slip into production undetected
You only find out about slowdowns when users complain or rankings drop
RUM data takes time to accumulate - you need faster feedback
Manual Lighthouse tests are inconsistent and time-consuming
Different team members get different results depending on their setup
You can't reliably compare before and after a change
What you can monitor
Automated Lighthouse Audits
Schedule full Lighthouse audits to run automatically. Performance, Accessibility, SEO, and Best Practices scores - all tracked over time without manual effort.
Multiple Test Locations
Run tests from different geographic regions to understand how distance and network conditions affect your global audience. Catch CDN issues specific to certain regions.
Consistent Baselines
Every test runs in the same controlled environment. No more "works on my machine" - get reproducible results you can trust for before/after comparisons.
All Performance Metrics
Track FCP, LCP, TBT, CLS, Speed Index, and Time to Interactive. See exactly which metrics improved or degraded after each change you make.
Performance Alerts
Get notified when key metrics like LCP or CLS exceed thresholds. Know about issues shortly after a deployment, not days later.
Historical Trends
Track how your performance scores change over time. See the full history of your Lighthouse audits to understand trends and validate improvements.
Screenshot Filmstrips
Visual filmstrips show how your page renders over time. Identify visual bottlenecks like late-loading hero images or layout shifts.
Opportunity Detection
Get Lighthouse's optimization recommendations automatically. Prioritize fixes based on estimated impact and effort required.
Network Waterfall Analysis
See exactly how your page loads with detailed request timelines. Identify slow resources, render-blocking scripts, and optimization opportunities.
Automated testing, actionable insights
Add URLs to monitor
Specify the pages you want to test regularly. Focus on critical pages like homepage, product pages, checkout, and landing pages.
Choose test frequency and locations
Set how often to run tests (every 4, 8, 12, or 24 hours) and from which geographic locations. More frequent tests mean faster regression detection.
Automatic testing begins
VitalSentinel runs Lighthouse audits on your schedule. Results are stored and compared against previous runs automatically.
Get alerted on regressions
When a metric drops below your threshold, you're notified immediately. See exactly what changed and when it happened.

Problems we help you prevent
Get alerted before issues impact your users
Real scenarios, real solutions
"A third-party script update tanked performance, but you didn't notice until users complained."
Regular synthetic tests running every few hours would have caught the regression quickly, letting you roll back or fix before widespread impact.
"Performance testing is manual and inconsistent. Results vary depending on who runs the test and when."
Automated synthetic monitoring provides consistent baselines for every deployment, making performance part of your QA process.
"You need to prove that performance SLAs are being met, but you only have sporadic manual tests."
Scheduled synthetic tests provide continuous evidence of performance levels, with historical data for SLA reporting.
Catch regressions before users do
Set up automated Lighthouse testing in minutes. Know about performance issues before they impact real users.
